setCustomValidity does not work for Popup LOV's
I am using APEX 20.2 and I am calling apex.item("name").node.setCustomValidity("message") for several items on a page.
All items display the red outline plus my custom message EXCEPT for the items that are the Popup LOV Type.
When I examine the item in my browser, I can see the proper class has been applied (apex-page-item-error) but the CSS rule to apply the red outline is being overruled by another CSS rule. Also, I can see the placeholder location where the message should appear, but it is still empty.
This application is using the Universal Theme.
